This recipe calls for 4-10 garlic cloves. Garlic clove size varies drastically (from giant to very small), so coarsely chop your garlic to taste. In this recipe, I used 9 garlic cloves (but remember, we're an Italian family and garlic is a staple!) and we used a mix of large, medium and small garlic cloves, which essentially came out to roughly 2 tablespoons.
Also, (need I mention the Italian thing again?), we love spicy, so we use 2 teaspoons of red pepper flakes, which will leave this spicy dish 'sitting' on your tongue - which we love. You may not, so please spice as you prefer!
